Reel Echo gives the perfect simulation of those great 50's tape echoes with some important added features:  Warble control to simulate the slight pitch deviation you get from any driven tape' system.  Lo Fi control - Rolls off the high frequencies of each successive repeat, just like tape does.  Tube/Solid State control - You can choose either sound.  Up to 1.5 seconds delay time.  Sound on Sound - Hit this button and play on top of the lick you just recorded.
